This invention relates in general to window construction and more particularly to a window construction in which one or more sashes may be swung in relation to the window frame to render both sides of a-sash accessible from one side of the frame.

An object of this invention is to provide compact, safe, simple and eificient means providing for the swinging of a window sash in relation to its frame quickly and conveniently to enable access to both sides of the sash from one side of the window so that it can be cleaned, painted, and repaired without leaning or climbing out of the window on the part of an operator.

.Another object of this invention is to provide novel means in a swinging window construction for conveniently, efiectively and expeditiously connecting and disconnecting a window sash and counterbalancing means therefor to enable the sash to be secured in its frame for normal sliding movement in relation thereto, disconnected and swung in one direction to an open position while remaining slidable in relation to the frame, and thereafter restored to normal slidable relation with the frame. 7

A further object of the invention includes the provision of novel means in a double-hung swinging window construction for securing one or more sashes in normal slidable relation with a frame,

disconnecting one or more of the sashes from their respective counterbalancing means, enabling sequential swingin of the sashes in, relation to the frame to provide access to both sides of the sashes from one side, of the frame while the sashes remain slidable in relation to the frame, returning the sashes to normal slidable relation with the frame, connecting them with their respective .counterbalancing means, and securing them in normal slid'able relation with the frame.

' Other objects of the invention include the provision of novel means in a window construction for disconnectibly connecting a sash and the count'erbalancing means associated therewith and for maintaining the counterbalancing means in adjusted position in relation to the frame and the sash while thesash and the counterbalancing means are disconnected. Additional objects, advantages and capabilities inherent in this invention will become readily apparent from the description thereof which follows.

This invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while there is shown therein preferred embodiments of the invention, it is to be understood that the 7 Claims.

The particular window construction herein disclosed for the purpose of illustrating the invention comprises a frame I I which maybe of wood, metal or other suitable material, having up ally'mounted therein in parallel spaced relation with one another and in operative association with counterbalancing means comprising counterweights 4, sash cords l5 and pulleys l6 which are rotatably mounted on the frame II. The frame is provided with spaced guides l1, preferably of metal, arranged adjacent the corresponding edges of the sashes 2 and i3 and in cooperative relation with spaced hinge members I8, which are secured to the sashes at the adjacent edges tlrereof. Thelhinge-"members 18 *are provided with shoes 19 which are arranged for cooperative sliding relation with the guides l1. As shown in Fig. the arrangement and con-'- figuration of the guides H, the hingememhers l8, and the shoes l9 are such a'sto provide for swinging and sliding movement of tthe:sash;in relation to the frame. To this end the guide may be in the form of an 11 or "H 'andthe-shoe conformed to engage opposite faces of adjacent portions of the guide in slidable relation therewith.

'iCQqperat'ing means are provided on each sash and 'the sash cord of one of its associated counterbalancing means for disconnectibly connecting th sash and the counterbalancing means, the sash cord of the other counterbalancing means being secured adjacent an end thereof to the sash preferablylatan edge'thereof in spaced relation with the connection of theifirst ment'lonedsash cord with thesash. The cooperating means include a supporting or housing member 20 carrying .a lever lmember 2| mounted adjacent one end .thereof for pivotal .movement in a ,plane .normal to "the axis of the ,pivot ,pin .22 which is received'in aligned openings .inthev housing member and the llevermember. The lever mernber 2| is provided withJan opening .23 arranged in spaced relation with the ,pin 12 .for pivotally receiving ahook portion 2 4..of-a connecting link 25, thereby forming an actuating arm on the lever between the pivot ,pin 22 and the lopening'fl. jThellink has alhookportionlii disposed in spaced relation with the portion 2.4 and arranged to 'be detachably received in ,an opening "21 in an end portion of a connecting member 28 which is secured to thefsa'sh cord adjacent one end thereof. The lever member T2| is provided adjacent'its end portion-remote from the pin 22 and the opening 23 with opposite latching portions'3fl and 3 The "housing member or carriage *is generally ti-shaped in cross-section, having generally rectangular opposite wall portions 32 between which'the lever member 2| and the link 25.are received, the'latchingportionsfil and "31 extending outwardly from one end of -'the'housing member. 'Thehousing member illlis conformed and arranged tobe slidably received in the -way33 whichisiprovided in the adjacent wall .of the frame II'with "the intermediate wall 134 of .the housing -mem'ber'preferably facing the way".33. Keeper means-in the form of a slot '35 is (provided withlnthe way 33 in the frame N formthe latching portion '30 .of the lever mem- "Each sash 'is provided with "a cut away portion or recess 36 arranged-in cooperativerspaced relation with the corresponding way 33 and the lever member 2| when th sashis'in normal position in slidable'relation with the frame. The cut away "portion 38 has an elongated .DoftionSO arra d-to receive *the Ehousing member 20' and a generally rectangular extension 5| arranged to receive "the :latching portion 3| of the lever member '21 and means for operating the Llever member 2|. The cut away portion is co-extensive at one end thereof with an end portion of the sash to enable withdrawal of the housing member 20 and the lever member 2| from the cut away portion 50 by sliding movement of the sash, as illustrated in Fig. 9.

The means for operating the lever member 2| may be in the form of a slide member 3'! provided with an angulated portion 38 having a surface '39 rarrangeilito engageia corresponding surface 40 provided on the latching-portion 3| of the lever member 2|. The slide member 31 is provided with spaced arms 4| and 42 arranged in cooperativerspaced relation with a movable am 43 rigidly mounted at one end thereof on a :Sha'ftM -which is rotatably mounted in the sash. The shaft 44 is rotatable by means of a lever '45 "or aknob 46 secured on its outer end; onmay be provided with a squared opening or slot 41 for receiving a removable key 48 for rotating it. In the form shown in Figs. 1 .to T6 .inelusive, the lever '45; isla relatively thin, flat memher having a surface arranged in slightly spaced relation with an adjacent surface of the sash. In .the'form shown in Fig. "8, the sashhas ,a-cut awayportion 49 in whichthe'knob 46 'is turnably inset. The slide member,31,the.arm43,,andthe shaft 44 may be operatively mounted in a casing 29 conforming withthe cut away portion iifi anfi secured thereinby means of screws29a.

"The arrangement of the slide member'ii'l, the arm 53 andtne shaft i l is such that uponlrotating the shaft I id'by means of the lever '45 the knob 46 or the key 48, from theposition shown in'Fig- 7 in an anti-clockwise direction, thelslide member 31 willjbe shifted to .theposition' shown inJFig. l9 and upon reverse .movement-of the shaft 44 the slide member 3 will be returned from the position shown invFig. "9 to the position shown .in Fig. I When the parts arein cooperativeposition, .as in Big. .7,r.such movements vresult"in.coriesmonding movements of the clever member .2.| which isnormally .urged in a clock-wise direction in relation to ..the.1of the -pin ZZ, viewing Fig. '1, by the operation of the counterbalancing means connected withthe-lever.memberthrough theilin-k 25.

Suitable guides or stops 52, 53 to limit swinging movement of the sashes, respectively, in one direction are preferably provided in the frame, as shown in Fig. 10. A frontal stop or guide 51 is provided adjacent the bottom of the frame, as shown in Fig. l, to prevent swinging movement of the sash l3 in-its lowermost position. In order to clear this stop, it is necessary that the sash be raised to the position shown in Figs. 3 and 6. The sashes also are preferably provided with cut away portions 54 in the edges adjacent the slides I! for receiving the sash cords secured therein. Weather stripping may be provided in generally conventional manner, but preferably being arranged as indicated at 55, 56, in Fig. 10, cut away portions 58 being provided in the sashes to receive it.

The operation of a swinging window construction embodying the invention may be described as follows:

With the parts in the position shown in Fig. 1, the lever member 2| and the slide member 31 being in the adjusted relation shown in Figs. 7 and 8, the member 45, the knob 45, or the key 48, as the case may be, of the sash I 3, is operated to rotate the shaft 44 and shift the slide member 31 to the position shown in Fig. 9, the member 45 being shifted to the position shown in Fig. 2. The sash I3 is then slid upwardly in relation to the frame to the position shown in Figs. 2, 7 and 8, in which the latching portion and the slot are in register. Upon such operation of the slide member and the sash, the lever member 2i is shifted from the position shown in Fig. '7 to that shown in Figs. 3 and 9 by operation of the counterbalancing means, thus disconnecting the counterbalancing means from the sash and enabling the sash 7 l3 to be slid downwardly to withdraw the housing 20 and lever member from the cut away portion 50. In this connection it should be observed that the shifting of the lever member 2| occurs automatically upon the coming into register of the latching portion 30 with the slot 35. Whereupon the sash may be manually swung with relation to the frame to the position shown in Fig. 5. Thereafter similar steps may be followed in respect to the sash l2.

When it is desired to return the sashes to normal slidable relation in the frame, the sash I2 is swung back into the frame and raised to the position shown in Fig. 5. The member is then operated to shift the slide member 3? from the position shown in Fig. 9 to that shown in Fig. 7 thereby connecting the sash I2 with its associated counterbalancing means and looking it in the frame in slid-able relation therewith. The sash 13 may be returned to normal slidable relation with the frame in like manner.
